The presentinvention relates to improvementsin beds, cots` and the lil're andthe primary ohjectfof the'inventionis to-provide a bed or cot of knock down construction perinitting the device to he collapsed into a compact form for storage or transportation purj as to per-mit mounting ofthe frame upon varions types of-supports.

Other objects and advantagcsof vthe invention will he apparent during the Course of the fol-lowing detailed description, taken in connection with the accompanying drawings forming a part of this speciiication Vand in which drawings:

portincluding a supporting frame B anda het bottom or rest-C, said framein the forni illustrated `in Figures l to 4 inclusive being suoported by upright cornenposts D.

eferring first to the-specific construction 1 ofthe Vframe B the same is ofsubstaIltially rectangular shape including parallel yside rails 5 and end rails 6. The rails 5 and 6 may either he formed of woodormetal,and

in the example shownfare formed of wood 1. .and substantially square `shape in cross'section. .The end rails 6 adjacent each'enld at their upper sidesare notclinedor recessed as :at 7, the notches hein-g of;;a llength,longitudinally of the rails equal kto the vvidt-h of lthe side'rails 5. Thcsenotches'? :are intended to receive the ends of the siderails' there- Ain as clearly shown in Figure 3 with the l ends of the side rails projecting beyond-1 the :end rails fora distance equal to the thickness 7- of the `corner posts D. The ends .of-the.v end rails 6 beyondY the outcrends ofthe notches 7 `are also of a length equal t0 the thickness of the corner posts D. The rails 5;: and 461at their overly-ing ends are yprovided lwith aligning drill holes 8`for removably receiving :a bolt 9 wherebytherails -andf4 6 are rigidly joined in an open rectangular shaped frame.

The projecting ,ends of the rails 5 fand; 6 form right angular shaped pocketsl zat each corner of the frame for receiving the central portions of the posts D. ThepostsDpreferahly have rounded upper and Vlowerends and are vvsquare shaped at'ztheir; intermediate portions for snugly fittingin-.the corner lpockets of the frame. VThe lprojecting-:ends of each lof the rails 5 and i6arevgprovided with horizontal bores 10 for receiving attaching loolts ll wherebyfthe corneriposts'" D are rigidly hol-ted `to vthe corneraportions of the supportingl frameB.

:Formed alongthe inner 'upper edgefof each side rail 5 Ais a rabbet l2-,the lower sur- ;faces .of-which ,are inclined.iinwandlyand "9' downwardly-as clearly shown in v'Figures 3 .andi-4. -The eri-ds lof tlieseirabbets-12 terminate inward-ly of the ends of theside.- rails and preferably :on va line *.With Ethe outer edges of ftheen'd rails 6. As `,wil-lfloe observed l" in Figure 1l, the lower edges of the inclined bottoms of the rabbets 12 are spaced above the upper surfaces of the end rails 6.

The bottom or rest C is preferably of wooden construction and embodies a series of longitudinal supporting strips 15 connected in parallel relation by a series of thin wooden cross slats 16 secured to the upper edges of the strips 15 as by nails or other suitable fastening elements 17. rlhe ends of the slats 16 project slightly beyond the outermost strips 15 and these projecting ends of the slats are intended to rest upon the inclined bearing surfaces of the rabbets 12 provided in the side rails 5. f The longitudinal supporting strips 15 are preferably of a length equal to that of the side rails 5 and are intended to rest freely upon the upper edges of the end rails 6. Each end slat 16 is reinforced by an overlying slat 16 preferably having a transversely rounded upper surface. These reinforced end slats are intended to have abutting engagement at their ends with the square ends 12 of the rabbets 12 for preventing shifting movement of the rests longitudinally of the supporting frame B.

lIhe inner or shallow portions of the rabbets 12 are of a depth equal to the thickness of the slats 16 so that the upper surfaces of the slats will align with the upper surfaces of the side rails 5. Recessing the side rails 5 into the end rails 6 not only gives rigidity to the assembled frame but also permits use of thinner supporting strips 15 to allow sufficient yielding of the rest. The ends of the longitudinal supporting strips 15 thru having bearing engagement upon the upper surfaces of the end rails 6 will prevent downward yielding of the end portions of the rest. lVith the ends of the slats 16 resting in the rabbets 12 it will be seen that the frame B is held against shifting movement both longitudinally and transversely of the supporting frame. f By observing Figure 4f it will be seen that when the weight is placed upon the rest C, the strips 15 and slats 16 will be flexed downwardly and that the ends of the slats will have a substantial bearing contact with the inclined bottoms of the rabbets 12 and not just line contact therewith as would be the caseV were the bottoms of the rabbets not inclined.

With the form of bed or cot A illustrated in Figures 5 and 6, saw horses E of the trestle type have been shown in place of the corner posts D for supporting the frame B.

The saw horses E include the usual head or cross piece 2O supported by the diverging leg pieces 22. The head piece 2O is preferably of a length equal to the width between the outer edges of the side rail 5 and each end of the head pieces at their upper sides are notched out as at 24 providing seats for the side rails 5 to engage upon for preventing shifting of the supporting frame longitudinally of the head piece. The saw horses E are preferably arranged inwardly of the end rails 6 and thus the frame B is prevented from longitudinal movement by engagement of the end rails with the saw horses. The heads 20 are notched at 24 for a depth suiiicient to prevent shifting of the supporting frame and yet retain the longitudinal supporting strips 15 out of contact with the upper edges of the heads. Owing to the spreading of the legs 22 it will not be necessary to secure the supporting frame to the saw horses to prevent collapsing of the bed or cot when erected for use.

By having the longitudinal supporting strips 15 substantially stouter than the cross pieces or slats 16, the rest will have greater tiexibility on an arc transversely of the rest than longitudinally thereof and which will be desirable for rendering the rest more comfortable. The endsof the strips 15 projecting beyond the terminal slats 16 aside from forming good bearings for the ends of the strips, also provide hand grips permitting ready and easy raising of the rest out of position in the supporting frame.

From the foregoing description it will be apparent that a novel and improved construction for beds and cots has been disclosed embodying a rest of such construction as to eliminate the necessity of employing coil springs, woven springs and the like for obtaining the desired flexibility. It will also be apparent that an improved mattress support has been disclosed embodying a novel type of collapsible supporting frame which may be mounted upon various types of supports and thus rendering the mattress support especially well adapted for use by campers and the like or in places where it is desired to store the bed or cot out of the way when not being used. It will further be apparent that an improved bed bottom or rest has been disclosed which may be very economically constructed and which may be used upon various types and styles of beds and cots.

Changes in detail may be made to the forms of invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims.

I claim:

' 1. A mattress support comprising an open frame including end and side rails, said side rails at their upper inner edges each being provided with a rabbet terminating inwardly of the ends of the rails and providing a shoulder adjacent each end of each rail, and a rest including longitudinal supporting strips resting upon said end rails, a plurality of cross slats fixed to the upper sides of the strips with their end portions resting in the rabbets of the side rails and with the terminally disposed slats in engagement with Cil 'said shoulders', and a stiiening strip secured to the upper side of each of the terminally disposed slats.

2. A bed bottom comprising a series of stout longitudinal supporting rails, a series of thin, readily flexible slats secured to the upper sides of the rails with the ends of the slats projecting beyond the outermost rails, and a stiffening strip secured to the upper side of each of the terminally disposed slats.
